This table shows the regions that were detected in each of the samples by genotyping microarray analyses and their characteristics; the location of the QTL on the linkage map (cM), the size in cM and the location of the QTL within the marker clusters on the linkage map of Nasonia (Desjardins et al., 2013). The QTL size is also estimated in Mb, by adding up scaffold sizes that were mapped to the genetic map by Desjardins et al. (2013). The QTL size can be larger than estimated because of gaps between scaffolds and a number of scaffolds that could not be mapped to the genetic map. Genotyping PCR was used to confirm the presence of heterozygous regions (N. vitripennis/N. giraulti) at the location of the QTL; the number of wasps with such a heterozygous region is given.
